See the Sharp New Image of an Iconic Black Hole

The iconic first-ever view of a supermassive black hole sports a dramatic new look, thanks to machine learning.

The galaxy M87 is located some 54 million light-years away from Earth. At its heart is a black hole that contains some 6.5 billion times the mass of our sun. That behemoth is one of two main targets of the Event Horizon Telescope , a coalition of radio observatories located around the globe. By combining data from these sources, scientists essentially constructed a telescope the size of Earth—powerful enough to capture details of bright matter swirling around the black hole.

When scientists created the initial image, they relied on a generic machine-learning system to fill in the gaps. When a distinctive ring-shaped image emerged from that process, that helped convince scientists that they were truly looking at a black hole. But the ring’s blurriness made learning more about the black hole difficult.

PRIMO runs on rules derived from what scientists expect black holes to look like, which the algorithm gleaned from training on a host of simulated black holes with varying characteristics—different masses, different spins, and so on. The result is a much more specialized algorithm.

This is like applying a tik tok filter to someone's face and calling it a 'HD image'. Hogwash!

🤔 How can you use observation to tell you if your theory is correct, when the observation is constructed using the theory?

Nonsense

LOL...and using Photoshop I have made it even sharper!

But still with hypoperfusin in the anterior wall

They are rotated with respect to one another; the maxima don't line up.

Sorta underwhemling, sorry.

Iconic? Purrr.

7 billion times mass of our Sun! Amount of electromagnetic radiation energy -EMR- that includes radio waves, microwaves, infrared, light, ultraviolet, X-rays & gamma rays (all are part of the electromagnetic spectrum) trapped within the giant rings of light alone is incalculable.

Still looks like the Firefox logo

Enhance

Couldn’t they just have coloured the first one in?

Taking a sharper look at the M87 black holeThe iconic image of the supermassive black hole at the center of M87—sometimes referred to as the 'fuzzy, orange donut'—has gotten its first official makeover with the help of machine learning. The new image further exposes a central region that is larger and darker, surrounded by the bright accreting gas shaped like a 'skinny donut.' The team used the data obtained by the Event Horizon Telescope (EHT) collaboration in 2017 and achieved, for the first time, the full resolution of the array.
